Parvovirus B19 (B19V) is a single-stranded DNA virus of the family Parvoviridae and genus Erythrovirus.[1, 2].

If a pregnant woman is exposed to an individual with parvovirus B19 infection, serology to determine parvovirus B19 immunoglobulin G (IgG) and immunoglobulin M (IgM) levels is indicated. o A positive IgG with negative IgM result indicates past infection and reassures that no risk to the fetus is 5.

Parvovirus B19 infection is common worldwide, and most persons who contract the virus are infected by 15 years of age.These patients do not test positive for IgM or IgG and remain contagious.11 Polymerase chain reaction (PCR) assays are preferred over less sensitive nucleic acid hybridization Parvovirus B19 in children with SLE. ParvovirusB19 IgM and IgG (r-biopharm, Darmstadt, Germany)] were used to determine the presence of specific IgM and IgG against parvovirus B19 VP1 and VP2. Levels>0.9 are considered positive. Results: Anti-parvo virus IgM antibodies were positive in 6 (11.1) patients and 3 (5.7) controls while anti- parvo virus IgG antibodies wereThe aim of this study was to test for anti-parvovirus IgM and IgG antibodies in adult pa-tients with HT.

Anti-Parvovirus B19 ELISA ( IgG).With a cut-off value of 5 IU/ml, 67.8 of blood donors were anti-par- vovirus positive (IgG), in agreement with the known infection level in adults. Serology is the method of choice for diagnosis of uncomplicated PVB19 infection. The determination of IgM and IgG should be preferably performed in paired serum samples.Parvovirus B19-IgM- negative ELA Test PKS medac cut-off positive. positive) was positive by a CE-marked parvovirus B19 IgG line blot. 2. Precision/Reproducibility Two separate precision studies were conducted to assess the precision of the ZEUS ELISA Parvovirus B19 IgG Test System. Keywords: parvovirus B19, chronic anemia, polymerase chain reac-. tion, immunoglobulins.In the remaining positive patient only specic IgM could be detected. Of the 13 parvovirus B19-positive patients, 11 tested positive for specic IgG (85), while 18 of the remaining 30 parvovirus INTRODUCTION. The parvovirus B19 is the only member of the family Parvoviridae known to be pathogenic in humans(1 ). This virus is widespreadThe results are summarized in table (1-1) reveled that in dialysis patients , five (10) were found to be anti IgG-B19 positive and 45 (90) were If recent infection has occurred, then the IgG should also be positive at that time.911,18 (Figure) If both parvovirus B19 IgG and IgM are negative, the woman is not immune and is therefore susceptible to infection.9,69 If she has had a recent exposure to the virus The presence of virus resp. infection may be identified by: Serology: Detection of antibodies by ELISA.Parvovirus B19 IgM Positive Control: 1 bottle containing 2 ml coloured yellow ready to use red cap.
